Aims Coronary heart disease is one of the leading causes of mortality in modern societies. The disease is associated with the lack of physical activity and the expression of some genes involved in blood cholesterol transportation. Adenosine triphosphate (ATP)-binding cassette transporters G5/G8) ABCG5 and ABCG8) is the expression of adenosine triphosphate-dependent box protein genes 5 and 8, a ...

background: ascorbic acid (vitamin c) is one of the most commonly water soluble vitamins. extra energy is necessary for the exercise is not often attributed to intake of vitamin c, long-term and intense exercise can lead to oxidative damage to cellular compounds and also contribute to muscle fatigue and decrease exercise performance. limited data are available regarding to the efficacy of vitam...

BACKGROUND A key barrier to achieving recommended intensity and duration of physical activity is motivation. PURPOSE We investigated whether a virtually present partner would influence participants' motivation (duration) during aerobic exercise. METHOD Fifty-eight females (M(age) = 20.54 ± 1.86) were randomly assigned to either a coactive condition (exercising alongside another person, inde...

The purpose of this study is to examine the effect of 30-minute duration submaximal running and roller skiing exercises, which are among the most important aerobic exercise models in cross-country skiers, on lactic acid levels. The study group comprised 6 female and 4 male athletes (age: 16.87 +/- 1.87 years, body height: 168.35 +/- 5.66 cm, body weight: 56.83 +/- 7.1 kg) who competed in cross-...

UNLABELLED BACKGROUND As patients with juvenile idiopathic arthritis (JIA) progress into adulthood, long-term outcome is determined by disease activity, physical and psychosocial development. Decreased aerobic capacity may play a critical role in health-related outcomes in JIA, since it has been linked with cardiovascular morbidity and mortality in late adulthood. The objectives of the curre...

Transient regional increases in brain activity associated with task performance result in elevated glucose metabolism greater than the corresponding increase in oxygen consumption (aerobic glycolysis). Aerobic glycolysis is also present in the resting adult brain but neither its regional pattern nor its mission is known. We studied the distribution of aerobic glycolysis in the resting human bra...

Part of the association between physical activity and low blood pressure (BP) may be a consequence of genetic selection. We investigated the association of genetic factors and physical activity in adolescence and adulthood with BP. BP was measured with a Finapres device in 71 monozygotic and 104 dizygotic male twin pairs using no antihypertensive medication. Subjects' mean age was 50.4 yr (rang...

BACKGROUND AND PURPOSE Prior studies suggest that aerobic exercise may reduce both the brain atrophy and the decline in fractional anisotropy observed with advancing age. It is reasonable to hypothesize that exercise-induced changes to the vasculature may underlie these anatomic differences. The purpose of this blinded study was to compare high-activity and low-activity healthy elderly voluntee...

Mycobacterium tuberculosis is one of the strongest reducers of nitrate in the genus Mycobacterium: Under microaerobic conditions, whole cells exhibit upregulation of activity, producing approximately eightfold more nitrite than those of aerobic cultures of the same age. Assays of cell extracts from aerobic cultures and hypoxic cultures yielded comparable nitrate reductase activities. Mycobacter...
